I have also noticed this here, and I think it is a bug in the kernel.

This problem used to exist pre-4.0 (or even pre-3.0, I don't remember)
and is the reason behind the SYNC_UMOUNT configuration variable (or
whatever it is called).  However, I recently noticed that this
variable does not do the correct job in current versions of pkg_comp
because the code does the sync after the unmount, which is incorrect.
Try to reverse this in the code and use the variable; you should be
able to workaround the problems.
